Abstract (en)

[origin: EP3842570A1] A method is disclosed for the generation of hydrogen and oxygen from a liquid feed stream comprising water. The method comprises passing an electric current through an aqueous electrolyte solution. Water is fed to the aqueous electrolyte solution by means of forward osmosis, wherein the aqueous electrolyte solution is brought into contact with a first side (16) of a forward osmosis membrane (11) and the liquid feed stream comprising water is brought into contact with a second side (17) of the forward osmosis membrane. Water permeates through the forward osmosis membrane from the second side to the first side by means of a difference in osmotic pressure between the liquid feed stream and the aqueous electrolyte solution. Further, a device (1) is disclosed for carrying out the above method.
